FIELD AND PURVIEW OF THE INVENTION

This concerns a tool useful for installing a pre-hung door, and a kit with and method use of the same. The tool has a body and jamb-holding finger(s).

BACKGROUND TO THE INVENTION

The installation of pre-hung doors can be fraught with difficulties and frustrating, especially for a do-it-yourselfer. Often it is difficult to install the door straight and level.

It would be desirable to ameliorate if not solve the problem. It would be desirable to provide alternative(s) to the art.

A FULL DISCLOSURE OF THE INVENTION

In general, provided is a tool useful for installing a pre-hung door, which comprises a body and at least one jamb-securing finger. The body can be removably attached to a building component about a door opening such as a 2×4, with the finger(s) for holding a jamb component of the pre-hung door.

The invention is useful in building construction.

Significantly, by the invention, the art is advanced in kind. A simple and efficient tool is provided that may be employed with another such tool to hold fast the door jamb in relation to door frame components so that shimming, shoring and securing of the door jamb in a straight and level orientation can be readily accomplished, even by the do-it-yourselfer. The invention is cost effective to manufacture and transport, alone or in a kit.

Numerous further advantages attend the invention.

The invention can be further understood by the detail set out below, which may be read in view of the drawings. The same is to be taken in an illustrative and not necessarily limiting sense.

The tool useful for installing a pre-hung door embraces a body and at least one jamb-securing finger. The pre-hung door may be an external door or an internal door. The body can be removably attached to a building component about a door opening such as a 2×4, with the finger(s) for holding a jamb component of the pre-hung door, for instance, with fasteners such as screws, nails, wire, certain releasable adhesives, and so forth. Spacer(s) may be employed in conjunction with the tool, especially to simulate the space that would otherwise be taken up by wall board such as, for example, gypsum board, which may be hung after the pre-hung door has been installed.

The tool, fastener and spacer may be made of any suitable material(s). Metal, plastic, ceramic and/or wood may be used.

A kit may be provided to include one tool and a fastener and/or a spacer. As well, a kit may be provided to include more than one tool with or without fasteners and/or spacers. The kit may be provided in conjunction with packaging.

Use of the tool to install a pre-hung door embraces supplying at least one tool and a pre-hung door; engaging a jamb component of the pre-hung door with the tool, typically through its finger(s); engaging a door frame component of a building structure into which the pre-hung door is to be installed, typically by employing the body of the tool; and shimming, shoring and/or securing the pre-hung door through its jamb. Fastener(s) and/or spacer(s) may be employed. The tool and any fastener(s) and/or spacer(s) may be removed after installation of the door.

With reference to the drawings, tool 100, 100′, 100″ can be employed with door jamb 3 that includes swinging door 4, intended for installation into a door frame of a building structure, which may have first, cripple stud 5, header 6, and second stud 7. Leveling device 9 such as a bubble level may be employed.

The tool 100, 100′, for example, made of aluminum, includes body 10, door jamb receiving first finger 11 and door jamb receiving second finger 12. The first finger 11 keeps distance between the door jamb 3 and door 4 even, for example, ⅛ of an inch for a ⅛-inch thick first finger 11. The second finger 12 can be optional, but its presence can assist in securement, especially for the do-it-yourselfer. Distance 13 between the insides of the first and second fingers 12, 13 is sufficient to embrace the thickness of the door jamb 3, say, being about ¾ of an inch. First orifice 15, which can allow a fastener to pass through to attach to the door jamb 3, may be of any suitable configuration such as a slot or a round or polygonal hole, for example, a round hole. Second orifice 16, which can allow a fastener to pass through to attach to a door frame component of the building structure such as a 2×4 stud, a 2×8 header, and so forth, may be of any suitable configuration such as slot 16′ or round or polygonal hole(s), for example, a pair of round holes 16″. The tool 100′ includes bracket ledge 19 on the side of the body 10 opposite the first and second fingers 11, 12, for example, to place the level 9 on during installation.

The spacer, for example, of nylon or polypropylene, includes body 70, and has width 73 for simulating the thickness of yet to be hung gypsum board (drywall), say, being ½ of an inch. Orifice 77, which can allow a fastener to pass through to attach to the cripple stud 5, header 6 or full stud 7, may be of any suitable configuration such as a slot or a round or polygonal hole, for example, a slot.

The fastener may be screw 80.

The tool 100″ is intrinsically adjustable. For instance, the body 10 can have inserted adjustable body part 10A, which may have knob 10K that may accommodate further accessories, and which can slide in along T-slot 10T. Adjustable clamp finger 11″ may be provided to engage various sized door jamb components with the adjustment, for instance, in opposition to the stationary second finger 12. The first orifice 15 can have bevel 15B to accommodate a bevel-headed wood screw 80B. The second orifice 16, which may be in a form of slot 16A, may also have bevel 16B to accommodate another bevel-headed wood screw 80B. In use, as with the tool 100, 100′, a spacer 70 may be employed with the tool 100″.

Accessories may be provided. For example, level-holding bracket 19″ may have fingers 19F and T-slot 19T, which may slide over the knob 10K. Door striker spacer 90, which may include knob 90K, has plate spacer finger 91 to go between the jamb 3 and door 4 at the countersunk position of a striker plate. The door striker spacer 90 can be affixed in relation to the tool 100″ by employment of locking plate 90L, which can include locking plate knob 90LK for grasping with the fingers and thumb, first T-slot 10KT for engaging the knob 10K of the tool 100″, and second T-slot 90KT for engaging the knob 90K of the door striker spacer 90.

Various additional accessories can be similarly provided.

The present invention is thus provided. Various feature(s), part(s), step(s), subcombination(s) and/or combination(s) may be employed with or without reference to other feature(s), part(s), step(s), subcombination(s) and/or combination(s) in the practice of the invention, and numerous adaptations and modifications can be effected within its spirit, the literal claim scope of which is particularly pointed out by the following claims:
